* Peak output current rating = 5.0A (<60 seconds, duty cycle <10%).

† Peak output current rating = 3.0A (<60 seconds, duty cycle <10%).

§ Peak output current rating = 2.0A (<60 seconds, duty cycle <10%).

Notes

1. Replace the input line fuse with the same type and rating.

Recommended: 2A/250V slow-blow fuse.

2. The sum of primary and auxiliary output currents from triple

output models -1AD through -4AD must not exceed 5.0A.

3. Hi-pot isolation is 2200 VDC from the input of the supply to

ground for 60 seconds.

4. All measurements are made directly at the terminals of the

power supply.

5. Peak-to-peak and RMS metering equipment must have a 20

MHz frequency response with probes and cables that main-

tain a frequency response of 20 Hz to 20 MHz. Output rip-

ple and spikes are measured directly at the output terminals

of the power supply with a 0.1 µF ceramic capacitor. The

probe ground band must make direct contact with the output

return or common terminal to prevent erroneous noise mea-

surements.

6. MTBF is calculated using the parts stress method in MIL-

7. Output voltage tolerance is measured under nominal load

current conditions.

8. Line regulation is measured under nominal load conditions

as the input voltage is varied from 85 to 265 VAC (ac-input

models) or from 36 to 75 VDC (dc-input models).

9. Load regulation is measured at 115 VAC or 230 VAC. For

single output models, load regulation is measured while out-

put current is varied from 0% to 100% of full load. With mul-

tiple output models, the output under test is brought to 60%

of nominal load; load current is then varied +40%/-30% of nominal while other outputs

are held at nominal load conditions.

10. Cross-regulation is tested by changing the load on the primary output from 50% to

100% of nominal load while measuring the voltage change on the auxiliary output

under test.

11. The FLU1-40, FLU2-40 and FLU3-40 series are approved to UL1950 (File E140439),

CSA22.2 No. 234 (File LR52335), EN60950/IEC950/DIN VDE 0805 (TÜV Licenses

R679206, R0097621, R9071501), and Austel CCL (Certificate A92/PS/004).

12. The FLU3-40 series has BABT/EN41003 approval ((NS/4199/123/R/604674).

13. The MDU1-40, MDU2-40 and MDU3-40 series are approved to UL544 (File E151357),

CSA 22.2 No. 601.1 (File LR52335) and EN60-601/IEC601-1/DIN VDE 0750 (TÜV

Licenses R9271474, R9271475, R9271476).

14. The DC2-40 and DC3-40 series are approved to UL1950 (File E140439), CSA22.2 No.

234 (File LR52335), and EN60950/IEC950/DIN VDE 0805 (TÜV License R9071501).
